iio: hudmidity: hdc100x: fix incorrect shifting and scaling

2016-07-27T15:42:21+00:00

commit 94bef000f1d4aa111f4ddda1482cf3b30ad069ce upstream. Shifting sensor data to the right 2 bits was incorrect and caused the scaling values + offsets to be invalid.

iio: humidity: hdc100x: fix IIO_TEMP channel reporting

2016-07-27T15:42:21+00:00

commit 09bc0ddaab6cab0fa95a67d5535ec772e2671193 upstream. IIO_TEMP channel was being incorrectly reported back as Celsius when it should have been milliCelsius. This is via an incorrect scale value being returned to userspace. Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio: humidity: hdc100x: correct humidity integration time mask

2016-07-27T15:42:21+00:00

commit 0e35cf5ce00d873d6e529d2b2cd7598d52438051 upstream. Apply the correct mask to enable all available humidity integration times. Currently, the driver defaults to 6500 and all is okay with that. However, if 3850 is selected we get a stuck bit and can't change back to 6500 or select 2500.

iio: convert to common i2c_check_functionality() return value

2016-02-27T17:17:43+00:00

Previously most drivers that used a i2c_check_functionality() check condition required various error codes on failure. This patchset converts to a standard of -EOPNOTSUPP Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron

Merge 4.5-rc3 into staging-next

We want the upstream staging fixes in here as well. Signed-off-by: Greg Kroah-Hartman

iio: dht11: Use boottime

2016-02-01T20:16:13+00:00

Wall time obtained from ktime_get_real_ns is susceptible to sudden jumps due to user setting the time or due to NTP. Boot time is constantly increasing time better suited for comparing two timestamps. Signed-off-by: Abhilash Jindal Reviewed-by: Harald Geyer Signed-off-by: Jonathan Cameron

iio: si7020: add support for Hoperf th06

iio: dht11: Simplify decoding algorithm

2016-01-30T16:27:13+00:00

The new algorithm uses a 'one size fits em all' threshold, which should be easier to understand and debug. I believe there are no regressions compared to the old adaptive threshold algorithm. I don't remember why I chose the old algorithm when I initially wrote the driver. Signed-off-by: Harald Geyer Signed-off-by: Jonathan Cameron

iio: dht11: Improve reliability - be more tolerant about missing start bits

2016-01-30T16:27:13+00:00

Instead of guessing where the data starts, we now just try to decode from every possible start position. This causes no additional overhead if we properly received the full preamble and only costs a few extra CPU cycles in the case where the preamble is corrupted. This is much more efficient than to return an error to userspace and start over again. Signed-off-by: Harald Geyer Signed-off-by: Jonathan Cameron
